Title: Manufacture of hormones of suprarenal cortex
IPC: A61K31/573
Filed: 1934-02-19
Abstract: Preparations of the hormone of the suprarenal cortex are obtained free from the toxic action of 1-(3 : 4 dihydroxy-phenyl)2-methyl-amino-ethanol-1, by treating the cortex, or the whole suprarenal capsule, or any preparations obtained from these, with formaldehyde or a compound capable of splitting off formaldehyde, such as formaldehyde-bisulphite orsulphoxylate.  It is stated that the formaldehyde forms condensation products, of unknown constitution, which are physiologically inactive.  Any excess of the aldehyde may be eliminated by adding ammonia.  The treatment with formaldehyde may take place in feebly alkaline, neutral, or feebly acid solution or suspension, or powdered suprarenal cortex may be treated with gaseous formaldehyde before the hormone is extracted. Examples are given.  Known processes for eliminating dehydroxyphenyl - methylamino-ethanol from preparations of the hormone of suprarenal cortex by treatment with potassium permanganate or hydrogen peroxide, are referred to.

Filed: 1919-03-07
Abstract: 136,730. Gilbody, F. H. March 7, 1919. Returning sound-box to starting-point; raising, lowering, and positioning sound-boxes. - Continuous reproduction of records is obtained by providing over the turntable an horizontal threaded shaft enclosed in a hollow bar, the threaded shaft being rotated by gearing from the turntable rim when the record is completed, thereby lifting the sound-box, returning it, and depositing it at the starting point. A vertical swivelling post B has at its upper end an horizontal arm to which is attached the bar F extending radially over the turntable. The threaded shaft J is mounted to rotate within the bar F and carries at one end a worm-wheel meshing with a worm G on a vertical shaft which has at its lower end a friction disk C lying adjacent to the turntable rim A. The shaft J has at the opposite end an eccentric K, the strap of which carries a depending rod N hooked at its lower end Z. The sound-box D carries an upstanding arm E, on which are formed a tongue P adapted to enter the thread of the shaft J and two curved arms S with hooked ends co-operating with ledges L on the bar F. On the completion of the record, the arm E engages a lug on the bar F, moving it towards the record centre, and bringing the disk C into contact with the turntable rim A. The shaft J is rotated and the eccentric K lifts the sound-box D, causing the tongue P to enter the thread J, and the hooked arms S to rest on the ledges L. The sound-box is moved towards the record rim by the screw shaft J, and, on its arrival at the starting-position, the hooked arms S fall through inclined slots on to spring tongues O, thus gradually lowering the sound-box on to the record. The inclined slots O are formed be. tween a fixed portion of the bar F and movable portions T which can be adjusted so as to form the slot at either end. The disk C is held by spring pressure against the turntable rim, and is released by suitable means as the members S reach the inclined slots.

A can body seamer having a stationary frame 11, a metal forming member 19 and a connecting rod 17 for supporting the metal forming member, comprises a rotary member 27 connected to the connecting rod for imparting oscillatory movement thereto, the metal forming member executing forming operations on successive metal workpieces as the connecting rod oscillates and first and second guide members 30, 31, each having a pivotal connection to the frame 11 but on opposite sides of the connecting rod 17 and each having a pivotal connection to the connecting rod. The frame also supports a forming mandrel 12 and a clamp 13 for the can body blanks 14, the clamp also acting as an anvil to take the impact of the bumper steel 19 during the side seam formation. The guide and stabilizer member 30 is pivoted at one end 32 to the frame and at the other end 33 to a lever 34 fixed to a cross-head 18 rotatably mounted on a shaft 35 carried by the upper end of the connecting rod 17. The other guide member 31 has one end pivoted to the frame at 38 and the other end mounted on the shaft 35. In operation, can body blanks are supplied to the mandrel by feed means (not shown) where they are clamped in position and folded around the mandrel by wing clamps (not shown) to interlock the hooks 15a and 15b on the blank. These operations are carried out in timed relation to rotation of the crank-shaft 27 to enable the bumper steel to flatten the engaged hooks and form the side seam 40, Fig. 4. The guide members 30, 31 ensure that the bumper steel is moving vertically with substantially no horizontal component of motion at the moment of impact and the two members also relieve the frame of the shock load which is equally divided between them.
Patent GB-768474-A (GB)
Title: Improvements in the production of aromatic carboxylic acids
IPC: C07C51/275
Filed: 1955-03-01
Abstract: Aromatic di-carboxylic acids are prepared by oxidizing di-alkylbenzenes with aqueous nitric acid in the presence of 1-3 per cent by weight of the oxidation solution of a compound of vanadium, chromium, manganese or iron, or of mixtures of such compounds. Compounds mentioned are manganese carbonate, manganese dioxide, alkali-metal permanganates, ferric nitrate and vanadyl sulphate.  The oxidation may be effected by heating a mixture of aqueous nitric acid of a concentration of 10-50 per cent by weight and the metal compound or compounds to boiling, and adding the dialkyl benzene.  The concentration of nitric acid in the mixture is maintained by continuously or periodically adding more highly concentrated nitric acid.  After separation of the aromatic di-carboxylic acid product, the mother liquor may be used for further similar oxidations without further addition of metal compound.  The process may be conducted in a continuous manner and under pressure and at raised temperatures. In examples: (1) p-diethylbenzene, 30 per cent nitric acid, and potassium permanganate are heated to boiling, further p-diethylbenzene and 98 per cent nitric acid being continually added during the reaction, and the precipitated terephthalic acid product is separated, the reaction liquors being used for a further similar oxidation with the addition of p-diethylbenzene and 98 per cent nitric acid; a similar oxidation omitting the potassium permanganate is described; (2) the oxidation of p-diisopropylbenzene with nitric acid in the presence of manganese carbonate, ferric nitrate and vanadyl sulphate to yield terephthalic acid is described.
